Anyone considering heading out onto the roads on Good Friday may need to reconsider their plans after a grim new weather alert warned of "supercell storms"
Residents in four Australian jurisdictions are bracing for a battering with the supercells expected to wreak chaos on roads on one the busiest days of the year for drivers.
"An outbreak of severe thunderstorms will affect parts of Queensland, New South Wales, the ACT and Victoria on Good Friday," Weatherzone said.

"(There's) a chance of very dangerous supercells as people hit the roads for the long weekend.
"An upper-level trough passing over southeastern Australia on Friday will cause the atmosphere to become unstable and primed for severe thunderstorms."
Meteorologists said the extremely "volatile weather pattern" will result in "widespread showers and thunderstorms" over central and southeast Queensland, as well as eastern and southern NSW and the ACT and Victoria.
Though any widespread storm system is dangerous, what's headed for the eastern states has the potential to become particularly hazardous, with the likelihood of "large-to-giant hail" having significantly increased.

Damaging-to-destructive winds are also on the cards, set to make travelling even more of a nightmare.
"This Friday's dynamic weather pattern will feature an unusually cold pool of upper-level air and a high amount of vertical wind shear (large change in wind speed and direction with height)," Weatherzone said.
"Some thunderstorms are likely to occur in the morning, although the most widespread and intense storms will hit during the afternoon and early evening."
The regions likely to be hit the hardest range from central NSW, all the way up to Queensland in the state's southeast, including both major metro areas of Sydney and Brisbane.
